FRAME FOR CIULTIVATORS.

SPECIFI'CATION forming part of Letters Patent No. 615,775,-c1atedDecember 13, 1898.

Application filed July 26,1898.

To all whom it may concern: 7

Be it known that we, MATTHEs ZoLLNER and CARL ZoLLNER, citizens of theUnited States, residing at Blackland, in the county of Rockwall andState of Texas,ha've invented certain new and useful Improvements inFrames for Cultivators and other Agricultural Implements, of which thefollowing is a specification.

This invention relates to cultivator-s, and particularly to an improvedwheeled cultivator-frame having spring-controlled cultivator-beamsprovided with new and novel means for attaching plow-points,harrow-teeth, and other various cultivating implements, as well asstalk-cutters and cotton-choppers.

The invention consists in the novel construction andarrangement ofparts, as will be hereinafter fully described, and set up in theappended claims.

In the accompanying drawings, forming part of this application, Figure 1is a top plan view of the invention. Fig. 2 is afront view. Fig. 3 is aside view. Fig. 4: is an enlarged detached perspective View of the plowor cultivator hanger. Fig. 5 is an elevation of a seat-post, showingmodified means for controlling the lever connected to the tongue. Fig. 6is a modified form of hook. Fig. 7 is a perspective view of the T-shapedstandard.

The same numeral references denote the same parts throughout the severalfigures of the drawings.

The cultivator-frame consists of plates 1, secured in place at each end,with an interval or space 2 between them, by angle-irons 3, from whichthe axles of the wheels 4 depend. The said plates 1 are secured aboutthe middle of their length to the short arms of two T-shaped irons 5,the long arms of which form fenders 9 and have openings for the bowedbrace-rods 6, attached at each end to the angle-irons 3. A suitable seat7 has a post 8 secured to the plates 1, said post having a slot 9. Thefenders 9 of the irons 5 project forward from the front of the frame,and the hounds 10 of the tongue 11 are pivoted by a rod 10 to saidprojections. A vertically-disposed inverted-T-shaped standard 12 isfixed to the hounds and has a lever 13 pivoted thereto. This lever hasnotches or Serial No. 686,968. (Na model.)

teeth 14 and extends through the seat-slot 9, where the teeth are keptin engagement with the bottom edge of the said slot by a spring 15. Amodified form of means for controlling this lever is shown in Fig. 5,the lever 13 working in a bracket 16 on the side of the seat-post 8 andcontrolled by a ratchet-wheel 17 and pawl 18.

Two or more bars 19 are adj ustably secured to the plates 1 by bolts 19,passed through the spaces 2. These bars are adjustable on the frametransverse the latter by simply loosening the said bolts 19. To one endof the said bars is pivoted, at 20, an L-shaped beam 21, the long arm ofwhich is looped or has a slot 22. The other end of the bars 19 has anupwardly and outwardly projecting hook 23, to which is attached one endof a spiral spring 24, the other end 'of said spring being secured tothe depending short arm 21 of the said beam 21. A modified form of thishook is shown in Fig. 6, where the hook 23 has lateral eyes orprojections 25 for the purpose of varying the tension of the spiralsprings.

The hangers 26 for plow-points or other cultivator implements areslidably secured upon the slotted ends of the beams 21 and have an arm27 pivoted at one end to. the said hangers and at the other end to akeeper 28, slidably held in the slot 22 by integral cars 29, whichengage the top edge of the slotted portion of the beams. These hangershave hand-levers 30 in convenient reach of the operator on the seat 7,whereby the hangers may be raised and lowered independent of the saidbeams, while the spring-tension of the latter imparts to the hangers andthe im plementsthey carry sufficient resiliency for the proper operationof the same except in case of an implement becoming hung or en gagedwith a large obstruction. Then the hanger is operated to raise the plowor im plement. are all to be raised together or simultaneously the lever7 is operated to raise the rear of the frame, which elevates the beamsand hangers. When this lever is drawn back slightly, it will raise thetongue and hounds and relieve the horses of the weight thereof.

We do not wish to limit ourselves to any particular material or size inthe manufac In case the plows or implements.

ture of the frame and its parts, nor the application of the same, norany special implements to be attached thereto.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is-

1. The combination, in a cultivator-frame, of a series of plates havinga space between them, angle-irons to which the plates are secured ateach end, the middle irons to which the said plates are secured, and thebowed brace rods passed through the depending portion of the said middleirons and secured to the said angle-irons.

2. The combination, with the frame, of the bars adj ustably secured uponthe frame,hooks projecting from one end of the bars, beams pivoted tothe other end of said bars, and the spiral springs connecting said beamsand hooks.

3. The combination, with the frame, the bars adjustably secured to theframe, and

the spring-controlled beams pivoted to the said bars, of the hangersslidably secured to the beams, an arm pivoted to the hangers, and thekeepers pivoted to the said arms and slidably connected to the saidbeams.

4. The combination, with the frame, and the bars adj ustably secured tothe top thereof and having hooked ends, of the looped or slotted beamspivoted to the other ends of the bars, springs connecting one end of thebeams with the hooks, hangers slidably secured to the other or slottedend of the beams, an arm pivoted to the hangers, and a keeper pivoted tosaid arm and working in said loop or slot, and having, ears, as setforth.

In witness whereof we hereunto set our hands in the presence of twowitnesses.
